Got my Vectronix Terrapin & compared it t my Swaro

Re: Got my Vectronix Terrapin & compared it t my Swaro

My conclusion with mile shooting is that windage and other ballistics behaviour that I cannot clearly characterize make reliable hits at one mile not possible. I've had 4/5 hits, then 1/5 hits for no good discernible reason other than wind changed. So hits can be made no problem there, but 'reliable' dope that gets you somewhere on steel every time, like you can do at 800-1000 yards for example, no. Maybe it's because I am shooting across canyons where wind is quite variable. Maybe one can do better in a farm in flat Iowa.

Maybe a heavier projectile like 375 or larger Cheytacs are better for this application.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

With the cost of .338 Lapua Magnum ammunition I try to maximize return-on-investment between time, ammo, and fuel by putting wind flags out at 500, 1000, and 1500 yards/Meters.

No sense pissing away shooting opportunities wondering why a miss wasn't a hit.

Does that make it unrealistic as far as combat or ELR hunting shooting? Depends where you are in your crawl-walk-run progress and how much money you have. The Terrapin should tell you if you're past your capability and comfort zones.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

in our mile shooting area, we are flying Scenars and whatever over canyons... we can certainly put out wind flags as you recommend, which would help, but it doesn't indicate what the wind is doing up higher off the ground. In our areas it's like the wind is swirling around, bent from it's straight lines by these canyon and hilltops. But we are going to add wind flags right at the top of the hill that is our backstop in an attempt to better read wind conditions.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

It's always gonna be that way that far until some of the variables change, whether that means a better bullet, different caliber, something the conditions across that much distance is too unpredictable to reliably say the round will hit every time or every 3rd round.

You can build a dedicated ELR rig, and perhaps adjust the caliber, or shorten some of the problems down by using the latest and greatest, gain twist, monolithic solids, etc, but at the end of the day, any tiny variation from you too is gonna be big that far.

I would hyper focus on 1500m, work that to death while creeping up to a mile and then noting all the changes from 1500 to 1800m. But making big jumps, like people do, 1000m to 1800m without hitting every detail between you are missing out on a lot information most take for granted. There is reason people work up every 100 yards to 1000 yards. Yet people usually don't do that, they jump in the deep end and then wonder why things are not lining up the same. Most of the time it maybe terrain you can't place something every 100 yards that far away, but if you think about it. It makes little sense to hit 1250, 1500, and then 1800+ without solid data in between, at these ranges it is more important then inside 1000.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

Lowlight that is the best advice on ELR I've heard in a long time. I can say I've been to fast in jumping out to 1770. I've had a mental bookmark for developing dope every hundred yards from 500 out with my 338LM... just haven't had the patience to do it... every time I get out to BLM I rush thru my 800 and 1100 yard and go right for the mile. i need to slow down, and do exactly as you said and I'll have a much better chance at understanding beyond 1500.

thanks for the post.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

Getting back to Terrapin subject. I'm having a problem - perhaps you could pinpoint the cause and suggest a solution?

<span style="font-weight: bold">Environment</span>. Light wind, overcast. Some pine trees and bushes between 26 and 30 meters away. Beyond them visible through the "windows" between the branches are: a car at 106 m, and behind it a house (vinyl sidings) at 115 m. Slope angle between 0 and 2 degrees down. <span style="font-style: italic">Bushnell Fusion 1600 confirms these ranges reliably and repeatably, using different modes - Bullseye and Branches.</span>

I set 3dOn in my PLRF-05, and expected it to give me three readings: 27m, 106m, 115m.

<span style="font-weight: bold">My problem.</span> No matter what I do, Terrapin gives me only "27m" - the range to the branch nearest to the "window" of the Line of Sight to the car at 106m. I verified that "3dOn" is indeed set on. Unit Built-In Test runs and passes fine.

Has anybody seen this? If it's an operator error - what's the likely cause and how to correct it? Is there a way to test the unit to make sure it functions correctly? <span style="font-style: italic">"Gate" probably works, as when I set it to the nearest value "200m", it doesn't give me any measurement - there's nothing visible beyond that house at 115m.</span>
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

Is the 27 meters reading flashing? If so you need to punch the button again, it will give the next reading.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

Nope, "27m" is <span style="text-decoration: underline">not</span> flashing - it behaves as if it <span style="text-decoration: underline">didn't</span> take more than one measurement.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

Sounds like your 3D is not functioning, you might try turning it off and re-activating it.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

Well, after multiple attempts and experiments - there's a big change. Once in a while it does give me 3 ranges (27m, 30m, 106m). The farthest object detected seems to be the car - never the house behind it (except through a different "loophole" where there's no other object between the brush and the house), no matter how I aim. And <span style="text-decoration: underline">most of the time</span> it just gets stuck on the brush - i.e., doesn't even notice the car behind it, even though it's well-visible (judging by the reticle, there's unobstructed window of roughly 10x10 mils).

So, 3dOn is active, it is functioning somewhat (as I could get it to work <span style="text-decoration: underline">occasionally</span>, but it just refuses to function properly through the brush... WTF?
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

Thanks to Peter for his detailed explanations of F-class Open, for which I am currently putting together a rifle. Voice of experience is very helpful.

The main question I have regarding this thread is:

Why does having a rangefinder matter when shooting competitions at known ranges?

I must be missing something here (which is not unusual...)
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

Anyone left their Terrapin out in sub zero conditions for a day or two? I know that my Swarovski LRF seem to slowdown and the buttons become difficult to work. Do the Terrapins suffer this also???

Duc
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

There is no guarantee that any rangefinder is going to consistently range any three targets at varied distances just because you decide you want it to. If it hits a car it probably will not range anything else in your line of sight. If the brush you are ranging at close range is fairly thick it may not punch through it to the next target. I suspect you are just expecting more from this function than it can deliver.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro



"Look guys, all these previous post are Bullshit! I think it's pretty well understood the quality of these units, yet no one is posting how well the terrapin is ranging whatever particular target ( larue sniper target, IPSC torso, 12" plate), whatever, within your weapon's effective range. Also how well your first (or second) round hit probability has improved while engaging targets at unknown distances. Was'nt that the main reason for investing in a quality unit in the first place?"




That was my hope.
My testing has been off a tripod and the results have been what I had hoped for.
5" plate @ 350 yd, able to read difference between plate and backstop. Difference was 2 yd.
6" plate @ 400 yd. same result.
8" @ 500, same result
45% IPSC (6"X13") @ 600, gtg
10" @ 700, gtg
16" @ 800, gtg
Full IPSC @ 900, gtg.

Unit was tested along with a Swaro, and while I've had good results with my Swaro it was out classed in this test.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

I used my Terrapin out to 1980m last week on man sized targets. Some of which were camouflaged painted, so it worked well.
sunny and warm with a heavy mirage. The targets were then shot and all ranges were accurate giving solid impacts based on the shot.

The small aiming point is much better than the large donut of the Swarovski. We discussed this that the aiming point beyond a 1000m was useful.

If you want to step from your typical consumer based LRF to an actual tool, the Terrapin is it.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

Mouse, the beam divergence at 27 yds is under 1/2 inch vertical and around 2inches horizontal. Most if not all of the beam is being reflected. There is simply nothing left to strike the next target. If you want to shoot through bushes at close range you need to carefully pick a hole and try not to hit the brush. In the case of the car being ranged and not objects behind it, All of the beam is reflected. Take it out and range through trees at longer distances and see how it works.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

I just played around with the TERRIPIN. It is capable of aiming through little bitty holes at colse range while ranging more distant targets. If I attempted to range a single twig at 25 yds with a tree 300 yds in the background the results were mixed. Sometimes it would range the twig, other times it would range tree and sometimes it would range both. It is simply a matter of what the beam struck and how it was reflected. If you want to range through brush at close range use the Gate function.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

I guess I expected that when I aim clearly through the hole in the twigs that appears big enough for the beam to get through, I'd get a reliable reading of the reflecting object there - the car in this case. I could understand if when aiming at the twig itself it returned only the twig, and when aiming clearly between the twigs - if it returned only the car or only the house (depending on what remote object in particular was at the "cross-hair". What really bothered me was that 99.9% of the time I was getting only the twigs, not the remote object at all - despite that most of the time I was aiming either at the car or at the house, and clearly away from the twigs.

Adding to my frustration was the fact that Bushnell seemed to have no problem giving me either the twigs or the car depending on whether I measured in" bulls eye" or "brush" mode.

The idea to use "Gate" is good, and I thought of it. Unfortunately Gate works only at 200 meters and father, while this particular setup is between 27m and 160m.

I must add that I'm getting some darn good results with Terrapin also. But this use case bothers me. Of course an operator's error is not excluded yet at all - but it would help to know what it could be.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

Get out and play with it. Do the math and figure the ht./width of the beam at the distances you are ranging. At 25 yds you should easily slip the beam through a 4 by 4 hole. Finding out exactly where the beam really is in relation to the reticle is a must.

The small divergence of the TERRIPIN will make the 3d function more finicky up close than one with much larger divergence. The same thing that causes problems up close allows the TERRIPIN to shine at distance. Try ranging a deer on flat ground at 1000 yds with the Bushnell. The beam on the Bushy is four times as tall as the TERRIPIN.

There is much more to operating a rangefinder than being able to scroll through the functions.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

There is a certain amount of offset in the beam to the crosshair at close range, rather like the bore to crosshair in the scope. In this case, the beam is offset left, convergence is normally set to max standard range. Try setting up so the car is at the far right edge of the opening, which should center the bean on the hole. The Terrapin beam is visible in NVG's, so if you have some available you can spot the beam location compared to your aiming mark.

I see!! So it may be that I'm bouncing this thin beam off a twig instead. Thanks for pointing this out - I'll experiment with it and report. <span style="font-style: italic">Update: turned out the beam did bounce back from twigs - twigs I apparently considered too small to interfere.</span>

This is exactly my point.

What you call "small divergence" should mean that when I aim at the car through a large-enough hole (say roughly 6in x 6in at 27m), I should get just the car and only the car, every time.

Re: Got my Vectronix Terrapin & compared it t my Swaro

Chill sir, the comment was directed to the masses.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

I played a little more. I put the TERRIPIN on sandbags and shot through some holes. The beam would slip through some amazingly small spaces. If I have time this afternoon I intend to cut some holes in a paper target and try to verify exactly where the beam is in relation to the reticle and also verify the shape and size.

I have intended to do this before now but this thread has aroused my curiosity to the point I'm going to gitterdun. I have a PVS 14 so it may be possible to see strikes on paper well enough to determine size,shape, and location.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

<span style="font-weight: bold">Update</span>. Taking these two terms "small divergence" and "beam offset" deeply to heart, I experimented more. In short, success. The long version may benefit others, so here it is.

First I tried offsetting the aim a little to see if it might help. In my case it didn't. Then I explored that "natural loophole" more carefully, and found that it wasn't as clear of obstructions as it appeared to me at first under that less-than-perfect light. The clear areas were maybe of the size of the "cross-hair" circle of the reticle, maybe a pin width less. All the rest of the window had very thin (between 1/8 and 1/4 inch) twigs crossing it. So it looks like this precise beam was bouncing back at me from those thin twigs. Then after careful looking I found a spot in that window just a little larger than that aiming circle, and used it. Immediate success - repeated reliable 3d: range to the window and range to the car (or to the house, using a different spot). At these distances the beam seems to be perfectly aligned with the aiming reticle - I didn't notice any offset so far.

In summary: the system works, and the operator should be very attentive to the window details - twigs and obstacles that other units might not notice, get recognized by this one. On the other hand, ranging through mesh near the unit was smooth as castor oil.

Ain't they nice.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

As a matter of fact, yes - very much so.

Must add that I didn't realize before not only how narrow the beam is, but how small an object would bounce it back. Also, was pleased with how precisely the beam is aligned with the crosshair.

All in all, money well-spent.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: aldvsix</div><div class="ubbcode-body">Two questions:

First, does the Terrapin calculate the line-of-sight distance to the target or the horizontal distance? I've seen different people say different things about this.

MikeP states the Terrapin calculates only line-of-sight distance. https://www.snipershide.com/forum/ubbthreads.php?ubb=showflat&Number=3032444#Post3032444

Sendero_man states the Terrapin provides a "corrected distance" to the target based on elevation, which suggests to me that what you are actually getting is the horizontal distance to the target. http://www.snipershide.com/forum/ubbthreads.php?ubb=showflat&Number=2862671#Post2862671 Perhaps I am just misreading Sendero_man's post?

I note that the Terrapin manual uses the term "slope distance", and there is a brochure from Vectronix for the PLRF 10C (the one with the built-in inclinometer) that appears to define "slope/slant distance" as the line-of-sight distance, as opposed to the horizontal distance:
plrf.jpg

http://vectronix.ch/userupload/850_PLRF_Brochure_EN.pdf

I would assume that the PLRF 10C is able to calculate horizontal distance based on the the line-of-sight distance, the angle measured by the internal inclinometer, and a cosine function. I can't tell whether the Terrapin has an internal inclinometer, but if it doesn't, I don't know how it would be capable of measuring anything other than the line-of-sight distance. Perhaps someone from PRG could weigh in on this issue?

Second, when ranging a target, does the shooter care more about the horizontal distance or the line-of-sight distance? From a practical standpoint, if the line-of-sight distance to my target is 1000 yards, but the target is at a 30 degree angle above me, the horizontal distance is only going to be about 870 yards. Which distance do I need to plug into my scope?

Thanks for any input folks can provide on these questions.
</div></div>

Has anyone determine if the measurement from the Terrapin give you the horizontal distance or the line of sight distance?

Just got mine and it's amazing piece of hardware versus my Leica 1600. Only function I think I'll miss from my Leica is the continuous read/measure function. Other than that, the Terrapin is built like a tank and measures every distance I threw at it.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

Ryo, I've raised the question before. In total, the information from Vectronix is confusing. I believe it is measuring true LOS, not the projected horizontal distance.

I want to measure true LOS and angle and let me input that into a ballistic computer which has different options for computing the effective horizontal distance for elevation lookup.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

Yes it measures the LOS distance, not adjusted horizontal. This is based on my observation and conversations with Vectronix (in the opposite order
smile.gif
).

I had the opportunity to compare Terrapin with the Fusion 1600. Suffices to say that TERRAPIN shined, and Fusion didn't impress me all that much in this test.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

It's definitely LOS. Finally remembered to test it comparing it with another LRF. Just aimed at a pole, and aimed up that pole, and have both LRF's measure the same value.

Too bad.. was hoping to save time from needing to calculate the horizontal distance for long range shots.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

look into Bryan Litz book on slope shooting... there are various ways to calculate the come-up given a degree of slope. It's clear you're better off doing this outside of the LRF, until that day when LRFs and ballistic calculators wtih easily upgradeable software are one and the same unit.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

I agree with cali_tz. "Slope range" is always line of sight distance and only the more expensive Vectronix units do that calculation, but since any long range shot is going to involve complex ballistic calculations besides true distance (horizontal or "gravity" distance) so saving a bundle on a rangefinder and using your iPhone (try an app called "Theodolite Pro") to determine slant angle and azimuth with high accuracy. The sensors in the iPhone are very sensitive and accurate.

Now, having just thought of it, I'd like to see how attaching an iPhone 4S to a Terrapin's eyepiece using Theodolite Pro would work. Theodolite Pro (there's a free version too) is an app that uses the camera and superimposes reticles and other information on the screen showing azimuth, vertical angle, longitudinal angle (side to side rotation or "scope cant", gps location and it allows you to measure delta angle between two objects and calculate distance based on a known measurement (like the size of a vehicle or height of a flagpole) based on angular measurements. It will then take a photo with all the data included that you can email or sms text. You will still have to enter the data into your PDA or Kestrel Horus software to calculate your ballistic solution, but you'll have precise, recorded data and image of the target.

In other words, Theodolite Pro does everything a more advanced Vectronix unit would do, and more, except do the math for the ballistic solution, for about 20 bucks (if you have an iPhone 4S), and if it can be successfully mounted behind the eyepiece of the Terrapin (and I have no reason to think it can't be), the range will be likewise superimposed on the image.

What I need to know is if there is a screw thread on the Terrapin eyepiece and what the size/pitch is so I can have an adapter machined for my iPhone to fit my Mod Armory iPhone PVS14 mount.

Assuming I get a Terrapin (working on that), my plan is to set up the Terrapin as I describe and attach it to the side or top of my Leupold spotting scope using my LaRue SPOTR setup. I'll have a micrometer adjustable mount made for the Terrapin so that I can zero and register the rangefinder reticle with the reticle in the scope, so the unit can be used easily and quickly to acquire and range a target, shoot a photo of the target with range and theodolite data appended, transfer the slant and azimuth data manually to the Kestrel Horus software and generate a firing solution without fumbling around at all.

It MIGHT be possible to get the Theodolite Pro app to Bluetooth the data to the Kestrel as well, which would automate things even more. I'll check on that.

At present, I use an actual Zeiss TH4 optical scale reading theodolite for long-distance rangefinding beyond my Leica's 800 yard range and I'm looking forward to a more elegant solution to rangefinding that doesn't require two setups and lots of math.

Since this is my first post, I'll give a little background on myself. I'm retired LE and I currently shoot a Sako TRG-42 .338LM with US Optics SN3 5-25 scope, a LaRue OBR .308 with Springfield Armory scope, and an AR-10T .308 with a Springfield Armory scope.

Re: Got my Vectronix Terrapin & compared it t my Swaro

Has anyone gotten false readings off of dust? While ranging across a gravel road a car went by and it wouldn't range past the dust until it dissipated.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

Yes, it will pick up dust if it's thick enough or close enough. In the case of an isolated patch of dust simply activate 3D. It should range the dust and show a flashing result. Punch the range button again and it will show the next target ranged.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

In my case, Terrapin is faster than most everything civilian I used. And quite decisive: it will either give you the range - on the spot, or tell you that it can't - again on the spot. Unlike Bushnell Fusion that (again, in my case) always requires coaxing - e.g., Fusion would give me "no range", "no range", "OK it's 850m", "no range" (occasionally it would give the results on the spot - but those were rare occurrences). While I didn't get outstanding ranges from Terrapin (mostly close to its specs) - it would immediately tell me that "this small boat is 900m" and "that small boat is beyond my range", no hesitation whatsoever. I really loved it. One very convenient, reliable and ergonomic device.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

so far the only down side I can see is the price. But hell I cant out shoot my current rangefinder so it don't matter.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

I got a Terrapin, and think it is just about the most important piece of shooting equipment that I own. The more precision ranging measurement really helped me improve my long range shooting.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

It's a nice piece of kit. I wish it was 7x, but it's still nice. If it was 7x it would be awesome!!
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

given the range at which you are going to guarantee ranging, which is less than 2000 yards in bright sunlight, I find the 5x reticle quite sufficient for ranging a 24x24" plate at 1800 yards, and probably we can range something quarter that size if we had a tripod to hold it steady.
 
Re: Got my Vectronix Terrapin & compared it t my Swaro

Update: Finally ordered my Terrapin, supposed to ship today from Botach Tactical, should be here the end of next week. Then I have to start figuring out the adapter for my Mod Armory iPhone adapter and get it made.

If I'm lucky, Mod Armory's new PVS-7/PVS-14 clamp-on eyepiece adapter for their iPhone holder will also work with the Terrapin.

It's a two-piece split-ring that slips around the fixed eyecup flange on the PVS-7 and those PVS-14s that also have a non-removable eyecup flange and then attaches to the iPhone holder.

It works great on my one PVS-14 with a fixed flange, I just hope the Terrapin eyecup flange is either removable or the same thickness as the PVS-7 flange, otherwise I'll have to have one custom made.

Not trying to rain on your parade but good luck with getting something from Botach. It's hit or miss with those clowns.

Yah, I heard that after I ordered. However, if they don't ship it today, and send me the tracking number as promised (I called them earlier) I'll just chargeback the credit card and buy it somewhere else.
